Omas have released this limited edition pen which is inspired by the surface of Mars. The Marte (Italian for Mars) pen is made of rose gold which is made to look like the surface of mars, the pen is in fact a map of mars featuring its dusty deserts, its mountains and craters. There are four rubies on the pen which indicate the four landing points of the martian probes. The frozen carbon dioxide caps are represented by two carats of diamonds encrusted onto each cap.
